Whilst birding at Taj Dam a large group of Alpine Swift flew in and started feeding in the wadi bottom and near the water that had escaped from the dam causing pools. This is an uncommon breeding migrant & passage migrant, where it occurs widely in small numbers mainly in the west of the Kingdom. Part of the population stays over spring and summer to breed in the southwest highlands in craggy areas and feeds widely over areas where food and water are plentiful. Occasionally large numbers can be seen together such as the flock we saw with over 100 together regularly seen.
